辽宁省气象VPN网络是气象数据地面宽带传输网络的备份系统,采用隧道技术、应用L2TP协议,在互联网公用网络平台上建立气象虚拟专网。通过VPN备份网络,可以实现省市县三级气象主备线路的切换,缩短网络故障引起的实时业务中断时间,为省市县三级网络提供灵活和高效的数据传输。笔者首先简要介绍了VPN虚拟专用网,分析了辽宁省省市县三级气象广域网络架构,阐明了双线热备的实现策略,对省市县三级VPN备份网络的故障处理与日常维护方法进行了详细说明。
Liaoning meteorological VPN network is meteorological data terrestrial broadband transmission network backup system, the use of tunneling technology, the application of L2TP protocol in the public Internet network platform to establish meteorological virtual private network. Through the VPN backup network, you can switch the meteorological main and backup lines at provincial, prefecture and county levels to shorten the real-time service interruption caused by network failures and provide flexible and efficient data transmission for provincial, county, and tertiary networks. First of all, the author briefly introduces the VPN virtual private network, analyzes the meteorological wide area network structure of three provinces in Liaoning province, expounds the realization strategy of dual-line hot backup, and analyzes the troubleshooting and daily maintenance methods of the three-level VPN backup network Described in detail.
